A few weeks ago, I revisited my thesis on Comfort Systems USA (NYSE: FIX) as a pure-play HVAC stock riding the secular tailwinds of cooling demand, sustainability retrofits, and data center buildouts. I still think FIX has further to run, and you can read why here. But I can also understand why some people might think the stock has already priced in a lot of its upside … after all, it’s up over 100% in the past 6 months.
Luckily, there’s another name in the same ecosystem that hasn’t run nearly as hard … and it actually offers something extra. Here’s why this HVAC stock is B rated (Buy) according to our Zen Ratings system:

Ferguson (NYSE: FERG) is best known as a plumbing distributor, but HVAC is now one of its fastest-growing businesses. That means you’re still getting exposure to the same HVAC labor shortage and infrastructure upgrade themes that have powered FIX higher.

On top of that, Ferguson adds diversification with its Waterworks segment, tied to public works, pipelines, and municipal projects. This is a huge plus … because while residential demand can swing with housing cycles, infrastructure and water are steadier, longer-term drivers.
